Aneurysm III: Interprofessional Care01:26

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
Anastomoses01:19

Anastomoses

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They are most common in...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Summary

Visceral aneurysms, though rare, pose rupture risks. Custom aortic endografts with fenestrations offer a novel solution for complex cases unsuitable for standard stent grafts.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Endovascular Techniques

Background:

  • Visceral aneurysms are uncommon vascular conditions with a significant risk of rupture.
  • Standard stent graft repair is limited to patients with favorable anatomy, excluding many complex cases.

Observation:

  • Two patients presented with complex visceral aneurysms (hepatic artery pseudoaneurysm, aneurysmal vein graft degeneration) lacking suitable anatomy for conventional stent grafting.
  • These challenging cases required innovative endovascular approaches.

Findings:

  • Successful treatment was achieved using custom-made aortic endografts featuring a single fenestration for the target visceral artery.
  • The endografts were combined with visceral covered stents to ensure adequate sealing and exclusion of the aneurysms.

Implications:

  • This custom endograft technique provides a viable treatment option for visceral aneurysms in patients with unfavorable anatomy.
  • Further long-term studies are necessary to confirm the durability and safety of this endovascular approach.
